TERMINAL CLAMPS FOR BATTERY POSTS.

To all whom it may concern: z

. Be it known that I, FRED O. RATSCH, a citizen of the United States,residing at Neillsville, in the county of Clark and State of isconsin,have invented certain new in Terminal Clamps for Battery Posts, of whichthe following is a specification.

In carrying out the present invention, it is my purpose to provide aterminal clamp for the posts of batteries that may be applied to andremoved from said posts in a simple and expeditious manner.

A further purpose of the invention resides in the provision of such aclamp that is so constructed as to reduce the liability of the clampfrom becoming corroded, generally due to a loose connection between theclamp and battery posts. I

A still further purpose of the invention is the provision of such aclamp that is adapted to be employed in conjunction with batteriesequipped with varying types of posts, my invention beingcharacterized byits simplicity, durability and efficiency, and one that may bemanufactured and'marketed at small cost.

A still further purpose of the invention is to provide such a clampwherein the same comprises end elements, capable of being disassembledfor permitting of the removal of parts in the event of the same becomingbroken or otherwise .impaired for eflicient use.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connection. with theaccompanying drawings, the invention-residing in the construe tion,combination, and as claimed.

In the drawing forming part of this application, like numerals ofreference indicate similar parts in the several views, and wherein:

Figure 'l-is a side elevation of my improved clamp and positioned upon abattery post.

Figure 2-is a detail cross section thereof, and

Referring to larl'y to Figure 1 5 designates a storage battery, 6 theusual round post, and 7 the terminal wire of the engine ignition systemformed with a just described invention, the

bevelled end 8. The elements are not of the essence of my same bein-g ofstandard makes, and-being merely shown in the drawing for moreadequately disclosing the relationship of my invention thereto.

My device-per se, embodies the provision of an inverted substantiallyU-shaped bracket member 9, formed upon one on with a projecting conicalsocket member '10, adapted for receiving the said bevelled end 8 of theterminal wire 7, this wire being soldered or otherwise rigidly securedwithin. said socket member 10.

The longitudinal wall of the bracket member 9 is provided centrally uponits under surface, and at one end-th'ereof, with a round-shaped socket11, within which is engaged the projecting pin 12 formed upon the upperend of a removable plate 13, which has one face formed'with a depression13 for receiving a. projection 9 formed upon the adjacent face of thisend of the bracket for consequently preventing the disengagement of thisplate, should the clamp ever become loose. The front face of this plate13 is arcuately shaped as at 14:, for permitting said plate to haveclose contact with the battery post 6, when the current is suppliedthereto. 7

Extending through a screw threaded. opening within the opposite end of.the bracket 9 is a bolt 15 having swivelly disposed upon the inner endthereof a head 16, adapted for \vedging engagement with the battery post6 when the said bolt 16 is turned in one direction, it being of courseunderstood that the end of this bolt outwardly of said bracket 9' isprovided with a ,thumb wheel 17, for this purpose.

In view of the above description, it will at once be apparent that whenthe removable plate 13 is positioned within the bracket 9, and the head16 moved in a direction away from this plate, the clamp may be readilypositioned upon the battery post 6, and upon a turning movement of thebolt 15, through the medium of the thumb wheel 17 in a forwarddirection, this head is moved into engagement with the post. forconsequently securely binding the clamp thereon. Should the plate 13become corroded, at any time, the clamp may be removed, and the plate 13cleaned or renewed.

It is believed by me that it will at once be apparent tothose skilled inthe art that I have provided a highly improved type of terminal clampfor battery posts, and one that will accomplish all of the functionsabove ascribed and even though I have herein shown and described thepreferred embodiments of the present invention, it is nevertheless to beunderstood that minor changes may be made therein, without departingfrom the spirit and scopeof the invention as claimed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters-Patent, is:

A terminal clamp for battery posts comprising a substantially U-shapedbracket, a clamping screw threaded through one side portion of thebracket, the bracket being provided at its inner surface and oppositethe said screw with an inwardly disposed hump, the bracket beingprovided at the inner surface of its intermediate portion and in thevicinity of that side thereof provided with the hump with a recess, ablock having a vrecess adapted to fitover the hump and provided with alug adapted to enter the first mentioned recess, that face of the blockwhich is opposite the screw being conceived and means for connecting-aconductor with the bracket at that side portion thereof upon which thehump is provided.

I In testimony whereof I afliX my signature.

FRED C. RATSCH.
